Buddha's life Teaching
Siddhartha was born a Hindu prince. A priest has predicted that he would become a wondering holy man. To prevent this, Siddhartha's father sheltered him. Siddhartha did not see old age, illness, death, or poverty until he was 29. When he finally did see such troubles, they upset him. He fled home to search for peace in a world of suffering.
Four Noble Truths
For six years, Siddhartha starved himself, but this sacrifice did not help him find the answers he sought. Then he sat under a fig tree and mediated until he found understanding. This gave him insights to reality, which he called the four noble truths. First, existence, is suffering. Second, that condition comes from wanting wanting what someone else has or wanting life to be different. Third, people can stop suffering by not wanting. Fourth, people can stop wanting by following the eightfold path.
